Description

1. Basic information
Brand: Allen-Bradley (Rockwell Automation)
Model: 1746-HSCE
Type: High speed counter module
Second, functional characteristics
Two-way counting capability:
The A-B 1746-HSCE module has A bidirectional counting capability to detect movement in either direction, making it ideal for applications that require accurate measurement of an object’s position or speed.
High resolution support:
x2 and x4 count modes are available to take full advantage of high-resolution orthogonal encoders for more accurate position and speed measurements.
High-speed input support:
High-speed inputs from orthogonal encoders and various high-speed switches are supported, and input pulse frequencies up to 50kHz are accepted, enabling precise control of fast motion.
Rate measurement function:
In addition to the cumulative counter, the module also provides a rate counter that determines the rate measurement by displaying the pulse input frequency in Hz. The rate measurement is determined by accumulating input pulses over a fixed period of time, and the rate period can be set to suit different application requirements.
Dynamic configuration:
Many parameters of the module are dynamic and can be changed without interrupting the operation of the counter, improving the flexibility and availability of the system.
Output control:
The module’s four current perfusion (open-collector) outputs can be controlled by user programs or modules, supporting a variety of output control logics.
